Is tap water safe to drink in Istanbul, Turkey? Yes, it is safe to drink. Tap water is pretreated in water treatment facilities by the ISKI (Water authority of Istanbul) and drinkable but:

Old pipelines and water tanks in buildings can cause water contamination. That is out of ISKI control. To avoid contamination, there is a trace amount of free chloride within the water, which is difficult to notice. Due to chloride and long retention time in pipe, the water in Istanbul may not taste and smell as good as soft natural water. Locals have a very delicate taste and prefer not to drink tap water. However, it is safe to say that tap water in Istanbul is safe and clean potable water.

Note:

If you are concerned with your health, we recommend buying bottled water. Especially if you have a sensitive stomach.

Source of Water in Istanbul, Turkey

Almost all of Istanbul’s drinking water (97%) comes from surface water collected from: 

  • Omerli-Darlik system – on the Asian side  
  • Terkos-Alibeykoy system – on the European side. 

Both consist of dams, reservoirs, water treatment plants, and pipelines.

Water Treatment Plant

Reservoirs that supply Istanbul are located within the metropolitan area. They are exposed to pollution from settlements without adequate sanitation. Conservation zones around the reservoirs control water quality. Within these conservation zones, construction and industrial activity are limited by four concentric buffer zones with increasingly strict ordinances the closer the zones are to the reservoirs. Despite this, there is little implementation of these regulations in the face of rapid and often unplanned urbanization. Illegal settlements have sprung up around the reservoirs and were legalized by their municipal administrations elected mayors.
